I'm using a Bauknecht washer in Berlin, Germany rental apartment. I don't have the model number, but during a cycle, it suddenly stopped and "F-05" was flashing. I unplugged the machine, waited for 5 minutes, and then restarted it. Right now it seems to be working. I can't find an "F-05" error code online. I've been using the machine for 3 weeks without any problems. Any ideas?
